@stefan ActivityPub explicitly supports html in posts and Mastodon renders that since 4.1 IIRC. The real question boils down to if Mastodon will implement some sort of editor for posts that supports inputing $SOMETHING (could be markdown or become etc) that gets rendered to html and posted that way. Technically not a big thing and as I said, other implementations have done this already. https://github.com/mastodon/mastodon/discussions/18872#discussioncomment-7886386 says it is on the roadmap, so I feel OK asking for it again after 2 years :)
